tissues of the body (GOST 26435-85). This approach saves time during the experi-
ment, and adequate results are obtained.

13.3.5 Expert evaluation
The research methods used to transform human perceptions into digital form are
subjective evaluation (sensory analysis), which includes reflecting, joining, and
gathering physical, psychological, and other data types. When different partici-
pants wear the same clothes, their psychological and physiological responses
may be different, for a number of reasons. It is necessary to define the different
reactions of the participants by a comfort-content scale, which is a unified refer-
ence standard. The scale can be designed from a group of words or corresponding
values (this scale is similar to semantic differential). The subjective evaluation
method is one of the important methods for studying the compression comfort that
results from the wearer’s psychological and physiological comprehensive reflec-
tion and using subjective intuition as the standard to compare and distinguish feel-
ings during garment wearing. To get the standard score, the group of participants
should be gathered in accordance with the common rules and approaches for
treating the results obtained.
The special scale can be used to evaluate people’s perception process and to elim-
inate subjective arbitrariness. This approach can be realized by using two kinds of
pressure evaluations - objective and subjective (Mengna, 2015). Fig. 13.4 shows
the subjective and objective scores of pressures relative to each other and appearing
during female dress wearing.
As Fig. 13.4 shows, to clarify the comfort perception, the expert assessment scale
was divided into three levels and was denoted with scores: “U” (uncomfortable) with
score 2; “E” (endurable) with score 1; “C” (comfortable) with score 0. Both param-
eters were obtained as average values after testing different female participants in
seven postures. Therefore, according to the possibilities and characteristics of both
methods, subjective and objective, it is important to use both to study the pressure
comfort. The evaluation of pressure must go through subjective evaluation and objec-
tive tests that conform with and complement each other.
